JORDAN ENGINE Filed 001; 16, 1951 2 Sheets-Sheet 2 Patented Aug. 623, 1932 UNITED STATES PATENT' OFFICE JOHN DqHASKELL, OF FULTON, NEW YORK, .A SSIGNOR "10 DILTS MACHINE "WORKS, INC., OF FULTON, NEW YORK, A CORPORATION OF NEW YORK JORDAN ENGINE Application filed October '16, 1981. Serial No. 569,292.

This invention relates to so-called Jordan engines for grinding wood or other substances suitable for making paper pulp. The Jordan type of refiner for paper stock comprises a cone shaped plug which is rotated within a correspondingly shaped shell or casing, both the plug and the shell being fitted with blades or bars for brushing out the fibers. The stock is admitted at the small end of the shell and discharged at the larger end. The plug is mounted in bearings which ermit it to be adjusted endwise to take up or the wear of the'knives on the plugand in the shell; The plug is usually rotated to give a peripheral speed of approximately 3000 to 3500 feet per minute at the larger end of the plug. It is the object of-this invention, while it incorporates the above conventional features, to

. provide a machine of much smaller size and designed expressly to be run at muchhigher velocity. It is intended that the speed of revolution in an engine constructed in accordance with this invention may be from 6500 to 13000 feet per minute at the big end of the plug. Such high speed of rotation of the plug creates a hydraulic pressure centrifugally which is particularly advantageous in the hydration of the fibrous material such as paper stock acted upon. An objection to such relatively high speeds in a Jordan engine is that there results an over heating of the stock. In the eiTgine built in accordance with this invention this applicant incorporates what is believed to be a new structure, in that he is water jacketing the entire shell. This allows cold water to be admitted and discharged continuously for maintaining the temperature in the shell below an excessive degree. On the other hand there are conditions where heat would be desirable, and in such conditions the chambered casing can be used for admitting hot water or steam if necessary, so that any desired temperature may be kept up.

The action of the out the fibers of the material and aid in the so-called hydration of the stock. This is accomplished by the cutting action of the knives or blades of the plug and shell and also by the Jordan engine is to brush pressure generated by centrifugal force. In order to control this pressure more accurately, the applicant has provided a pressure.

gauge on the discharge outlet, below a weighted relief valve or similar valvular controlling'device. In other words, the valve lever-shown and described herein can be equipped with weights to permit any amount of back pressure necessary to accomplish a given desired result. Or, the same type of wier discharge box as used in the conventional J ordan set-up can be employed with this invention.

The special construction and arrangement of the parts of this invention are illustrated in the accompanying drawings, of which Fig.

1 represents a side view showing all parts as assembled. Fig. 2 shows a portion of the end of this invention in section, showing the connection of a pump for augmenting the pressure of the material served to the shell and plug. Fig. 3 represents the connection of the discharge outlet of this invention in connection with a wier box of customary construction. I

Throughout the description and drawings the same number is used to refer to the same part.

Considering the drawings, a conical plug 1 is provided with superficial blades 2 of any desired form and extending usually lengthwise upon the surface of the plug. A shaft 3 carries the plug. Bearings 4 and 4' are provided for the shaft, and the housings 5 of the bearings are supported by the standshaft as set forth and the hand wheel 8 and lock wheel 9 fix the adjusted positions of the screw. By those devices the shaft may be adjusted lengthwise. The whole is borne by the machine bed 10.

The shaftis provided with a flexible or universal joint 11 by way of which the shaft is coupled with a motor 12.

At the right hand or smaller end of plug 1 are fashioned fins or small vanes 13 for directing the stuff. into the shell or outer casing 14. This casing has the internal blades 15, and awater jacket 16 having inletand' outlet openings or pipes 17 and 18. At the larger end of the casing will be noted the spacer rings 19 and 20 which will be again mentioned.

The casing 14 has an inlet housing 21 constructed with an inlet connection 22. Where the shaft passes through the inlet housing of the casing in connection with the body part of the shell. It will be here noted that the removable spacer rings 19 and 20, of which there may be any chosen number, are arranged between the end portion 26 and the left hand end of the shell 14, and that the shell has an annular surface corresponding to the shape of the ring. It will be likewise noted that the right hand end of the shell 14 has a flange which provides a surface of the same extent and shape as that at the left hand end of the shell and so shaped as to receive the spacer rings. As the blades of shell and plug wear in use, it becomes necessary to move the shell relatively to the left, to compensate for the wear; This is accomplished by removing the spacer ring, or rings from the positions shown and placing them at the right hand end of the shell- It is not intended to confine this invention to the precise shape or number of the spacer rings hereing illustrated.

The end portion 26 of the shell has an outlet 28 opening into the elbow 29 and leading to the discharge outlet 30. A valve casing as shown in Fig. 1 designated by number 35 has a post or standard 31 which affords a fulcrum for a lever 32. The lever acts upon the valve rod 33 of valve 34 by which the outlet from the shell is controlled. The external pressure on the valve is regulated by positioning the weights 36 on the lever as will be readily discerned from Fig. 1. To ascertain the pressure below the valve there is attached a suitable pressure gauge 37.,

Considering Fig. 2, there will be noted the connection 38 from the inlet connection of the shell to a pump 39. It is not intended to limit this invention to any particular form or size of pump, or to its operating means. The pump illustrated has an inlet 40.

the pressure upon the valve by the weights and lever described. Over-heating is taken care of by sending water through the water jacket, or heat may be applied by directing hot 'water through the chamber. The construction herein set forth enables the applicant to materially reduce the size, and therefore the weight, of the engine and yet to reach the same result as in the machines of usual construction and in the same or shorter time.

Having now described this invention and its use, I claim 1. In a machine of the character described, an external conical shell having internal blades and separable end portions having inlet and outlet openings, said shell having a chamber surrounding the same provided with inlet and outlet openings, a bladed conical plug, a shaft carrying the plug, means for adjusting the shaft lengthwise, said shell and said end portions thereof having surfaces of corresponding extent and shape at either end, spacer rings adapted to be arranged at either end of the shell to compensate for wear of the shell and plug, and the said rings being removable. a a

2. In a machine of the character described, a conical shell having internal blades and inlet and outlet openings, the said inlet and outlet openings being formedin separable portions closing the ends of the shell, the ends of said shell having surfaces of corresponding extent and shape, and spacer rings constructed to fit separably and to be arranged at either end of the shell between the said closing end portions and the body of the shell.

3. In a machine of the character described. a conical shell having internal blades and inlet and outlet openings, the said inlet and outlet openings being formed in separable portions closing the ends of the shell, the said shell having a chamber surrounding the same and provided with inlet and outlet openings. the ends of the said shell and end portions having surfaces individually formed of corresponding extent and shape, and spacer rings constructed to fit said formed surfaces and to be arranged at either end of the shell between In. Fig. 3 is illustrated an elbow from the outlet end of the shell and marked 41 connected to the wier box 42, which contains the built up partition 43 of separately removable plates, and the wier box has a suitable outlet 44.
